T all whmn it n/rty concern:

Be it known that 1,, EUGEN KUTHE, 'ailib- I ject of. the Emperor of Germanygand a resident of Frobeln, Siles a, Germany, have invented certain newvand useful Improvements in Apparatus for Making Lime Sucrate, of

which the following is a specification.

= This invention relates more particularly to devices adapted to mix finely-'comminuted or dust-like materials with a liquid; and its object is'especially to prevent the formation of' foam.-

It consists in the combination, with a suit-- I able liquid-chamber, of -a dust-feeding pipe, I

Imeans for'admittingthe liquid into said pipe in thin jets, means for agitating the mixture in said pipe, and in various details of construction that will be described hereinafter; Thedrawing accompanying this specifica 'tion' shows a sectional view' of -a device embodying this invention.-

The liquid-chamber orvessel A is provided with a centrally-disposed dust-feeding pipe (1-; Narrow orifices d are provided in the pipeh at c, and the bottom of the piper is open at gto communicate with the outer; part of the chamber A. The orifices'd may be made in the form of slots,-as shown in thedrawi'ng, or-r'ound openings (not shownican also-be used to advantage, A spiral c onveyerf is j ournaled to revolve in the pipe (6 to force the material therethrough. This conveyer may hedriven in any suitable manner, as by bevel.

gears j I (Indicated at the top of the figure iii-dotted lines.)

', This invention 1s p'artic-ularly adapted for bringing about-achemical action between a liquid and dust-like material, and in cause a' uniform actionxit is necessary that the particles of material are hrought'into contact with the particles of liquid in as uniform and even manner possible! Themixing apparatus set forth in this invention is used more particularly for-mixing sugar waters or juices Witlrchalk-dust- A series of cooling-pipes(representedby It) are provided in the-bottom of the chamber to be used in. the eventthat itis desired to cool themixture; a

The operation of this device is as foliows;

order to The chamber is filled with. liquid to a level somewhat above the orifices (Z, and-the material is introduced through the pipe I' As the material passes downl-t'hrough the pipe a it comes in contact with th'ethin streamsof the liquid which flow in through the orifices and becomes mixed therewith." The spiral conveyer ber Any foam produced by the mixing process or by the action of the conveyer rises as at z and it will be noted thatthe level of the liquid should be kept above the orifices to prevent the foam from passing into the pipe (1.

Having thus described my inventiomwhich which will readily suggest themselves as com 'ing within the scope thereof, what I claim, and desire tosecure by Letters Patent, is-

1. In an apparatus for mixing dust-like ma terial with liquids,-t'he combination of a vertical dust-"feed pipe, having openings in its upportion of said pipe, a vessel adapted toconmunicating with the lower end thereof, where the "pipe and the mixture thus formed be disv essel. r v v.

2. In a mixingapparatuathe combination: of. a chamber for a liquid,'-a feed-pipe formaterial centrally disposed in said chamber and therein, and a conveyerin said pipe. 3. lncombination, a vessel for a feedpipe in said vessel, projecting near thebottom-thereof and open at its lower end and EUGEN KUTHE.
